Pulmonary Flashcards
MC pathogen and treatment for CAP (adult and pediatric)
Step. Pneumo *rusty (blood-tinged sputum)
*Give macrolide of doxycycline, amoxicillin for pediatrics
Cor pulmonale
Longstanding pulmonary HTN resulting in RVH, right atria enlargement, R sides heart failure, cyanosis, peripheral edema
*high risk in chronic bronchitis, a fib, and multifocal atrial tachy
What is the most common cause of transudative pleural effusions?
Congestive heart failure
What is the 2nd most common cause of typical CAP?
H. Flu (green sputum)
*seen in patients with underlying pulmonary dz
What is the most common cause of atypical, walking pneumonia?
Mycoplasma pneumonia
- seen in young patients
- bullous myringitis
In what population will klebsiella pneumonia cause severe illness?
Alcoholics , aspirations
*current jelly sputum , cavitation lesions
MC viral pneumonia cause in infants/young kids
RSV and parainfluenza
Typical pneumonia presentation
Fever, productive cough, Pluto this chest pain, rigors
-signs on consolidation such as increased fremitus, egophany, takes
Typical pneumonia organisms
S. Pneumonia
H. Flu
Klebsiella pneumonia
S. Aureus
Atypical pneumonia pathogens
Mycoplasma pneumonia (MC)
Chlamydia pneumonia
Legionella pnumophila
Virus
Atypical pneumonia presentation
Slight fever, dry cough, myalgias, sore throat, headache
- may ha e normal CXR
CAP inpatient treatment
Beta-Lactam + macrolide
Ceftriaxone+ azythromycin
Add on treatment if legionella pneumonia suspected
Levofloxacin
Add on treatment if PCP suspected
Bacterium + corticosteroids
Homan’s Sign
Calf pain with dorsiflexion, DVT
Classic triad of pulmonary embolus
1) dyspnea
2) pleuritic chest pain
3) hemoptysis
Sarcoidosis epidemiology
20-40y/o females of AA or Northern European decent
Sarcoidosis pathophysiology
Exaggerated T cell response of unknown origin causing inflammatory non caseating granulomas
PFT findings in RESTRICTIVE lung dz
- normal FEV1
- LOW lung volume
Skin manifestations of sarcoidosis
1) erythema nodosum
2) lupus Pernio*PATHOPNEMONIC
(Violet raised discoloration of nose, ear, cheeks-resembles frostbite)
Lab studies found in sarcoidosis
1) High ACE levels: secreted by the granulomas
2) hypercalciuria
3) eosinophilia
4) cutaneous anergy: diminished skin test reactivity
Classic presentation of Sarcoidosis
Respiratory s/s, blurred vision, erythema nodosum
PFT levels in OBSTRUCTIVE lung dz
LARGE lung volumes
-LOW FEV1
Lofgren’s syndrome/triad
1) erythema nodosum
2) hilarious lymphadenopathy
3) polyarthralgias/fever
*common sarcoidosis presentation
CXR and bx findings of pulmonary fibrosis
- diffuse reticular opacities
- honeycombing
- Ground glass opacities
*honeycombing on bx
